Here lies another lost cause. Invariably we are given no reason why we should save whatever it is that's threatened and, as a result, unless you actually know what's going on, the posters are meaningless.

The other thing that depresses me about them is they're so unsatisfying to look at that only rat catchers and carnival people read them.

I decided to add this one to the mix.

I liked the idea that, by making the poster as bland and conformist as all the other posters, there would be no incentive to read it. For most people it would be just another bit of tat on the street.

For those people who did read it however, there would be a curious journey to be undertaken.

I needed a truly hopeless cause.

Although the idea of the "Dolls' Hospital" has intrigued me since childhood, I settled on the "Balloon Hospital" for the simple reason that only a lunatic could imagine such a hospital existed.

I put a balloon in the background so that people wouldn't think I was talking about a real yet oddly named hospital and, as a final touch, I added a little knot in the balloon string with the caption "Don't Forget!"

As it happened I forgot. I was busy anyway, but I had the vague intention to turn up at 12 and see if anyone was about, so it was a pity I missed it.

I've since realised that because I didn't put a year on the poster I can put them up every year. One day I'll remember to turn up. Promise.

This is a good poster to be caught putting up, as most people just look at it briefly and think to themselves "Well, I suppose it's OK, heck, he's only trying to save a hospital, probably got a sick kiddie...."
